Product Description

We are dealing in a wide range of Silica Gel White. It is accessible in various mesh sizes as per the needs. Indicating is one, which is impregnated with cobalt chloride. In activated form, it has blue color that turns pink as the gel starts absorbing moisture. The intense blue color is an indicator of its complete activation. White color means that it does not contain any indicator. Hence, it do not change its characters post absorption of moisture and after activation. Nevertheless, both non-indicating and indicating materials do not differ in their absorption capacity, when material is delivered in fully activated state.
